RC401-69320 Hydraulic Gear Pump for Kubota KX91-2 Mini Excavator

   The RC401-69320 is a dual or triple-section gear pump (depending on the specific configuration) designed to meet the exact flow requirements of the Kubota KX91-2. It is engineered for high volumetric efficiency and features specialized wear plates that reduce internal leakage, even as the hydraulic oil temperature rises during intensive digging tasks.

• • • • • • • • • • • • • • • • • • • • • • • • • • •    - Direct OEM Fit: Matches the shaft dimensions, mounting flange, and port locations of the original RC401-69320 pump.

                                                    •    - High-Durability Housing: Constructed from high-strength aluminum or cast iron to resist pressure spikes and housing "bulge."

                                                    •    - Consistent Flow Rate: Optimized to provide steady hydraulic power, ensuring the excavator doesn't "stutter" when performing multi-function movements (e.g., boom lift and bucket curl simultaneously).

                                                    •    - Quiet Operation: Precision-ground gears reduce noise and vibration, extending the life of the drive coupling and seals.

Q1: What are the symptoms of a failing RC401-69320 hydraulic pump?

A: Common signs include slow cycle times (boom or arm moving slowly), a loud whining or growling noise from the engine area (cavitation), or the hydraulics losing power completely once the oil gets hot.

Q2: Should I change the hydraulic oil and filters when installing this new pump?

A: Absolutely. If the old pump failed due to internal wear, there are likely metal particles in the hydraulic system. Installing a new pump without flushing the system and changing the filters will cause the new RC401-69320 to fail prematurely.

Q3: Does the RC401-69320 include the drive gear or coupling?

A: Usually, the pump comes with the keyed or splined shaft. You will typically need to transfer your existing drive gear or coupling from the old pump to the new one.
